Sony TA-AX2 User Manual

SPEAKER CONNECTION
This amplifier has provision for two pairs of speaker systems —
system A and system B — which can be selected individually or
simultaneously by means of the front panel SPEAKERS selector.
Note that the speaker system A and B are series-connected.
No sound will be heard if only one of the speaker systems is con 
nected and the SPEAKERS selector is set to A + B.
Speaker power capacity
This amplifier is rated at 25 watts minimum RMS per channel with
an 8-ohm load from 20 - 20,000 Hz and may deliver an instan 
taneous peak power much greater than the rated power. Be sure
to use speakers with adequate power handling capabilities. Always
reduce the volume, when setting down or removing a tonearm or
when tuning an FM tuner across the band. Speaker damage may
result if these precautions are not observed.
Speaker impedance
The type 1 and type 2 models of this amplifier are designed to work
best with speakers with an impedance of from 8 to 16 ohms and the
type 3 model with speakers with an impedance of from 4 to
16 ohms. In any case it is important that the speakers ’ impedance
not be lower than 8 ohms for types 1 and 2 or 4 ohms for type
3. Otherwise the protection circuit may activate or the unit may
overheat when the amplifier is used at high volume levels.
Speaker cable type
Common 18-gauge lamp cord (the center conductor of 1 mm in
diameter) is fine for short runs. However, 16-gauge (1.3 mm) to
14-gauge (1.6 mm) may be needed for long runs to prevent ex 
cessive power losses in the wiring.
Connecting speaker cord to the amplifier
Connect each speaker to the corresponding amplifier speaker ter 
minals i.e. right speaker to the [R] speaker terminals and left
speaker to the [L] speaker terminals.

in the same direction. speaker are reversed, so two cones
move in the opposite direction.
Speaker placement
Here are a few suggestions for speaker placement that will assist
you in obtaining an installation with satisfactory stereo sound.
Normally, the speakers are placed on the floor against the narrower
wall of a room. The bass sounds can then be increased by moving
the speakers toward the corners, or decreased by raising the
speakers off the floor on suitable pedestals, and or moving them
away from the wall a moderate distance. If the speakers are posi 
tioned above the floor, do not place them higher than ear-level
while seated, since this produces an unnatural effect.
The distance between speakers, or the speakers and a listener
depends mainly on the room size. Generally it is recommended
that the speaker/listener relationship be an equilateral triangle con 
figuration (as illustrated).
If the speaker separation is too wide, an undesirable “ hole in the
middle ” effect occurs.
Wall
Best listening position
Place the right and left speakers in similar acoustic environments,
otherwise you will obtain unbalanced sound. For example, placing
one speaker near an open door or archway will decrease the ap 
parent bass from that speaker.
Best sound is usually obtained in a room with carpeting on the
floor, and having heavy draperies and upholstered furniture. Since
each room has its own individual acoustic characteristic, which is
a function of its size, construction and furnishing, some ex 
perimentation with speaker placement is generally necessary
before the correct balance of stereo image and bass response is
obtained. This will be time well spent, resulting in your enjoyment
of the maximum capabilities of your music system.
0 After these procedures are completed, pull on the speaker cord
lightly to see if the connection is secure.
